SPEQIFIUATION forming part of LettersPatent No. 657,510,'dated September 1 1, 1900.

Application filed January 13 1898; b'erial No. 666,553. (No model.)

To all whom it may concern:

Be it known that we, CHARLES L. BUOKING- HAM, of the city and county of New York,

and. EMIL GERMANN, of New York, (Brook:

lyn,) count y of Kings, State of NewYork, citizens of the United States of America, have invented certain new and useful Improve:

nents in Perforator-Keyboards, of which the following is a specification.

[O The perforating-machine shown in Figures 1 to 4 of the drawings is one of many which may be used with the invention herein claimed and is adapted to perforate holes in paper strips, in two rows, to form groups reps r 5 resenting either the Morse alphabet, an alphabet by which messages may be transmit ted and reproduced in type-writtencharacters, or groups of holes of. any desired'arrangement.

The general object of our invention is to provide an efiicien t, cheaply-constructed, and

rapidly-operating apparatus bywhich our perforating system may readily be adapted to prepare messages in different codes or to per:

forate strips of paper for other purposes; and

to this end our keyboard is preferably constructed in two parts one of which as a s u bstructure is permanently connected or employed with the perforator proper, while the second part,formingasuperstructure, is readily removable. The substructure is adapted to all codes and all alphabets; but the'superstructure is individual in character and is so constructed that it may readily be removed 5 and replaced in passing from one code to another, thus adapting our perforating system to many different codes by merely changing In Figs. 5 to 1 a small part of the apparatus. 16 are shown the two parts of our keyboard prepare messages in such manner that as received they may be printed in page form,

while in Figs. 17 to 20isshown the same substructure with a second different part adapting the system to the Morse alphabet. Su-

and circuits for adapting the perforator to keyboard superstructures with a common substructure, as there are many novel devices found in the two forms shown in the drawings which we desire to claim.

In preparing messages for reproduction in page form by a printing-telegraph machine we have found it desirable to perforate a definite number of characters for each line and to interpose an arbitrary group of per- I forations in the transmitting-tape between the end of one line and the beginning of the next, and for this purpose we have provided a register or indicator which is combined with an automatic locking device by which the perforating operator may know the positionhe has reached in a line, while at the end of the line the keys are locked against further operation until the lock is manually released. InUnitedStatesPatentNo.568,5l6, of September 29, 1896, an apparatus having a similar purpose is shown. In that case a type-writer carriage at the end of its line movement opens the circuit. of the perforator, thus arresting further operation until the return of said carriage. In using such an arrangement, however, there is a loss of time and labor in moving the carriage back at the end of each line for the commencement of the next, while the apparatus itself is complicated and expensive. In our present arrangement by merely pressing a key at the end of each line the lock is released, and at the same time a group of holes marking the commencement of a new line is perforated, whereas one or more keys must be pressed to mark the beginning of a new line after the type-writer carriage has been manually returned. Moreover, in the present arrangement while the register and locking 0 apparatus are moved a step at a time by the keys as each is depressed the additional resistance ofiered is so slight as not to be noticeable by the operator. i

Another no'vel feature of our keyboard for 5 perforating messages which are to be recorded in page form is a register for indicating the number of lines in a message that havebeen perforated. This is an important adjunct of our perforator system, since in the preparation of long messages a blank space must be left in the tape of sufficient length at theend of each page to allow time for the paper sheet to be replaced bya new one in the receivingprinter, and such result we accomplish by means of a step-by-step register which is actuated a step at a time in conjunction with the movement of the locking the end of each line.

ent invention a means whereby the space between letters and words may be increased in 5? perforating messages. This is an indispensable feature in preparing messages for transmission by the American; Morse code, since in such code there are characters which include long spaces. spacing before and after a letter often becomes necessary, while before and after a' word containing double spacing between letters the normal spacing must be increased.

This we accomplish by giving each key of the keyboard a capacity to cause the perforating machine to feed the paper tape a distance normally representing the character andalso, at the will of the operator, a capacity to feed 1 the paper an added distance, which shouldi This feature is also important in adapting our perforator for preparing cipher messages, for, as a rule, j double spacing is necessary between both letters and words to insure accuracy of transbe the same for allcharacters.

This we call a rubout. Following such operation a new line is commenced, as if no error or rub-outhad occurred, by pressing the keywhich makes the group of each newline. We also preferably employ the same key for the rub out; but when using it for such pur ose its operation must cause the feed-wheel of the perforator to move the strip one step less than it would in its normal operation, for otherwise a continuous series of dot perforations would not be produced; Currents from a tape thus prepared will not actuate the receiving-printer, nor would they, however long continued, in any ni'ann'erafieetthe printed message,'as during the transmission of a series of short pulses the printer merely remains quiescent.

The present improvements are particularly applicable to those machines shown in paten'ts 5N0. 568,512,0f0. L. Buckingham, E.'Ger mann, and J. W. A. Gardam, September 29, 1896, and No. 568,516, of C.
